3 Unstoppable Investments Everyone Needs in Their Portfolio

Do you just want to set it and forget it, so to speak? While this mindset is the essence of a buy-and-hold strategy, it also arguably oversimplifies it. Buying and holding is clearly a long-term thing, but that doesn't mean you should never check in on those stocks.

Here's a closer look at three of them you might want to consider adding to your portfolio while they're cheaper than they were just a few months ago.

Lackluster effectiveness. Given all of this, it's not surprising Merck was one of the few drug stocks that underperformed for the better part of the past couple of years.
